While i am playing in Italy campaign , After turn 64 precisely. The game just stops every time after i press (End Turn) the Ai doesn't do any moves , and i keep waiting forever.

Note : another problem happened , the game crashed later and Steam showed a message (Cloud Sync failed), and i had to retry. The cloud sync worked later. 

Then i tried validating game files through steam. Then the same problem persists.

Here's a screenshot of the problem.
